The plot2D() can plot funtion, equation, derivative, integral, differential equation, polar plot, parametric plot, animation. The independent variable must be typed as x for evaluation. The time variable must be typed as t.
for animation, input sin(x), then tick the auto Axis: button;
or add the time t variable, input sin(x-t), then click the auto t: checkbox;
or add the timer(t) function and change animation speed by the different t value, input sin(x-timer(t))
